A Scott County community remains in shock after a car accident that killed a 14-year-old girl and seriously injured two of her classmates.

The Hennepin County Medical Examiner ruled Anna Mary Bird's death an accident Saturday. She was a passenger in a car that veered off Murphy Lake Boulevard early Thursday evening and collided with a tree.

Bird, a freshman at Prior Lake High School, died at the scene of multiple blunt-force injuries, the medical examiner reported Saturday. The driver, 18-year-old junior Austin Knudson, and the front-seat passenger, 15-year-old freshman Sydney Stone, were critically injured and taken to Hennepin County Medical Center.

The accident happened at 7:10 p.m. Thursday evening, barely two and a half miles from the high school. According to a report from the Scott County Sheriff's Office, the vehicle was traveling northbound on Murphy Lake Boulevard, near the intersection of Sunset Lake Boulevard when it left the roadway and struck a tree.

The incident remains under investigation by the sheriff's office and the Minnesota State Patrol.

As news of the accident spread, social media filled with memorials for Anna Bird, a smiling, popular student and a member of the hockey and lacrosse teams. Mourners gathered at St. John the Baptist Catholic Church in Savage for a memorial service.
